Why Practice With PEwise?

You practice in a CBT-style environment built around the current NCEES PE Civil: Water Resources and Environmental exam specification. Each exam gives you a built-in practice calculator, the two Ten States Standards open alongside the questions (plus a panel for the Handbook you upload yourself), a timed session you can set to suit the sitting, and a detailed step-by-step solution for every question.

Sit Practice Exam 1 first to get comfortable with the interface and find your weak areas, then take Practice Exam 2 — an all-new question set — closer to test day. After each one you get your results broken down by NCEES topic, so you know exactly what to study next.

The Question Formats You'll Face

The PEwise simulator supports five question formats, and both 80-question simulations use all five, so nothing on exam day is the first time you meet a format.

Multiple choice

One correct option, as on most of the exam.

Select all that apply

All-or-nothing scoring, with no partial credit.

Fill in the blank

Type a numerical answer, no options to work backwards from.

Drag and drop

Match, sort, rank or label items.

Point and click

Click the right part of a figure.

NCEES describes its alternative item types with examples rather than a fixed list, so these are the formats PEwise supports — not a claim to cover every format NCEES may use.

Exam Mode or Study Mode

Every practice exam opens either way, and you choose each time you start.

Exam mode

Timed, with the scheduled break and question flagging, exactly as the exam runs. Solutions stay locked until you submit, so the score you get is the score you earned.

Study mode

Untimed. Check each answer as you go and read the full worked solution before moving on — the better way through a topic you are still learning.

Choosing your exam time

In exam mode you sit each 80-question simulation on standard time — 8 hours, with the optional scheduled break. If NCEES has approved additional time for you, set the same allowance here so you practice under the conditions you will actually have on exam day. PEwise does not grant or verify accommodations; NCEES and Pearson VUE handle those requests.

See Your Results by WRE Topic

When you submit, you get your score and a breakdown of how you did in every NCEES WRE knowledge area — so you know what to review next instead of guessing.

  • Your score out of the full question count
  • How many you answered correctly in each of the 12 NCEES knowledge areas
  • Every question reopened with its full worked solution and reference citation
  • Saved to your exam history, so you can see how your scores trend across attempts

It shows you where the points went, not whether you will pass — no practice score can tell you that.

Specification and References

These practice exams are written to the current NCEES PE Civil: Water Resources and Environmental exam specification, across all twelve of its knowledge areas, with the two Ten States Standards on NCEES's current WRE list built into the simulator — the same editions supplied at the exam. NCEES updates that list from time to time without changing the knowledge areas, so check the specification that applies to your own exam date.

These 2 Water Resources & Environmental reference documents are built into the exam interface and open beside every question:

  • Recommended Standards for Water Works — Ten States Standards, 2018
  • Recommended Standards for Wastewater Facilities — Ten States Standards, 2014

Licensing restrictions prevent us from distributing it directly, so you upload your own PDF:

  • NCEES PE Civil Reference Handbook — upload your own PDF; free from MyNCEES.

Your uploaded file opens in the same reference panel as the built-in documents, so you sit the exam with everything in one place. It stays in your browser and is never sent to PEwise.

Calculator Policy

For calculations, you have two options:

  • Use your own approved calculator — The NCEES-approved calculators for 2026 include:
    • Casio: All fx-115 and fx-991 models
    • Hewlett Packard: HP 33s and HP 35s models only
    • Texas Instruments: All TI-30X and TI-36X models
  • Use the built-in TI-36X Pro practice calculator available in the exam interface, so you can practice without a physical calculator to hand.

Note that NCEES identifies the TI-30XS MultiView as the on-screen calculator in its own testing software. The PEwise practice calculator is a TI-36X Pro — a different model, and not a replica of the official on-screen tool.

What PEwise Students Say

“The PEwise Water Resource and Environmental course presents content in a structured manner, beginning with fundamental components and progressing from that foundation. The course includes clear explanations of each topic, along with section quizzes designed to assess understanding and progress. The practice exam format is similar to that of the actual exam, providing a relevant evaluation tool for preparation.”

PE WRE Practice Exam FAQ

Two, totaling 160 questions. Both are full-length 80-question simulations with 8-hour timers. Practice Exam 2 is an entirely new question set rather than a re-mix of Exam 1.
Each 80-question simulation runs on an 8-hour timer with an optional scheduled break, matching the length and pacing of the computer-based PE Civil: Water Resources and Environmental exam. They are timed on purpose, so you build the stamina an eight-hour sitting demands, not just the knowledge.
Yes. Before you start an exam you can choose standard time or add 25%, 50% or 100% more, and there is a separate untimed Study mode where you check each answer as you go and read the full solution before moving on. These are practice settings available to every student; PEwise does not grant or verify testing accommodations — official requests go through NCEES registration and Pearson VUE.
Your score, and a breakdown of how many questions you answered correctly in each of the twelve NCEES WRE knowledge areas, so you can see which areas to review before the next attempt. Every question then opens for review with the correct answer and a full worked solution, and the attempt is saved to your exam history. The report shows where the points went, not whether you will pass — no practice score can tell you that.
Yes — every question has a step-by-step worked solution with the reference citation it comes from, available in the post-exam review. Solutions unlock when you finish a timed exam; in Study mode you see each one as you go.
All twelve knowledge areas of the NCEES PE Civil: Water Resources and Environmental specification: Project Planning; Soil Mechanics; Materials; Analysis and Design; Hydraulics — Closed Conduit; Hydraulics — Open Channel; Hydrology; Groundwater and Wells; Surface Water and Groundwater Quality; Drinking Water Distribution and Treatment; Wastewater Collection and Treatment; and Project Sitework. The topic breakdown of each exam is shown on its card above.
The two design standards on the NCEES WRE list are built into the exam interface and open beside the questions: Recommended Standards for Water Works (Ten States Standards, 2018) and Recommended Standards for Wastewater Facilities (Ten States Standards, 2014). The NCEES PE Civil Reference Handbook cannot be redistributed, so you upload your own copy — free from MyNCEES (account.ncees.org) — and it opens in the same panel. Your file stays in your browser and is never sent to PEwise.
The current NCEES PE Civil: Water Resources and Environmental exam specification, across all twelve of its knowledge areas, with the two Ten States Standards on NCEES's current WRE list built into the simulator — the same editions supplied at the exam. NCEES updates that list from time to time without changing the knowledge areas, so check the specification for your own exam date.
Yes. Your answers and progress are saved automatically in your browser as you work, so you can close the tab and pick the exam back up later on the same device. The simulator also includes the same scheduled break system as the real CBT exam, which locks the questions you've already viewed once you step away — exactly as it works at the testing center.
Yes — you can retake either exam as many times as you like while your enrollment is active. Every attempt is saved to your exam history, so you can watch how your scores trend as you study.
Single-answer multiple-choice questions are scored the standard way: select the one correct option. 'Select all that apply' questions are scored all-or-nothing — you must select every correct option and no incorrect ones to earn credit, with no partial credit, the same approach the real exam uses. After you submit, every question shows the correct answer alongside a detailed step-by-step solution, so you can see exactly where points were won or lost.
Five formats are supported in the PEwise simulator: multiple choice, select all that apply, fill in the blank, drag and drop, and point and click on a figure. Both WRE practice exams use all five. NCEES describes its alternative item types with non-exhaustive examples, so these are the formats PEwise supports — not a claim to cover every format NCEES may use.
The simulator has a built-in TI-36X Pro practice calculator you can open inside the exam interface, so you do not need a physical calculator to practice. You can also use your own NCEES-approved model — the approved list covers the Casio fx-115 and fx-991 series, the HP 33s and 35s, and the TI-30X and TI-36X series. Note that NCEES identifies the TI-30XS MultiView as the official on-screen calculator in its own testing software; the PEwise practice calculator is a different model and is not a replica of it.
They are included with the PE Civil Water Resources & Environmental course — there is no separate practice-exam purchase. Enrolling gives you both exams together with the video lessons, module quizzes and weekly live Q&A for the length of your access period.
Yes. Create a free PEwise account and take a 10-question WRE sample in the same simulator, drawn from these practice exams and covering all five supported question formats. No credit card required — you can start it from the Civil PE practice exams page.
No. They run only in the online simulator, because the point is to rehearse the computer-based-test experience — the on-screen reference panel, the calculator, flagging, the scheduled break and the timer. There is no printable or downloadable version of the exams.
No. Every PEwise question is written independently by our own engineers to match the format and topic coverage of the NCEES specification. PEwise is not affiliated with, endorsed by, or licensed by NCEES, and none of our questions are taken from an official NCEES exam or practice publication.
The NCEES PE Civil exam with the Water Resources and Environmental depth is computer-based: 80 questions in a 9-hour appointment that includes a tutorial and an optional scheduled break, with the NCEES PE Civil Reference Handbook and the listed design standards supplied on screen. PEwise gives you an 8-hour timer for the 80 questions plus the optional break, in a CBT-style practice environment that is not the NCEES testing software. Our PE WRE exam topics guide on the blog walks through the twelve knowledge areas.
Through NCEES, not through PEwise. Create a MyNCEES account at ncees.org, register for the PE Civil exam with the Water Resources and Environmental depth, meet any approval requirements your state licensing board sets, and schedule your appointment at a Pearson VUE test center. Enrolling in the PEwise course prepares you for the exam; it is separate from registering for it.
